For me it is the first time to see a low-level exploit implementation written in JS. Is the exploit done through a PS4's web browser? Quite interesting.

It is true that this is confusing for people who come across it for the first time, but it is easy to understand/remember once you know this feature.

It is worth noting that the else clause can also be used with while loops. [1]: https://docs.python.org/3.6/reference/compound_stmts.html#wh...

I would recommend JS stuff for middle schoolers. I agree Python is boring for Kids, but for kids under middle school, HTML + JS can be too much burden to learn. Besides the resources available on the web is not very friendly for Kids I thin

I don't know if I missed your point but right now I can export a private key using seahorse, a key manager program, very easily not using its password.

For people who say goto statements make spagetti, please consider looking at this goto use case in Linux, sock_create_lite() [1]. Imagine we make the same thing without goto here, is it gonna be more Don't-Repeat-Yourself, more readabl

That’s what I am thinking of. These days people use goto only to reduce spaghetti code in very specific use cases in C and nothing more.

Why they use "ASCII" for a distro release? This is so confusing name for people who don't know what Devuan is. I firstly thought some wierd guys created their own character encoding and claimed 2.0 version of ASCII.

Yeah, who would want to use ARM server, especially these days? Performance and power efficiency is not the only story nowadays. Most modern cloud servers rely on virtualization technologies. AFAIK ARM is very weak in running VMs. AMD's

Backward compability really matters. Windows has been always obsessed with compability. Guys in MS keeps max 255 characters long path just because of backward compability. Right after Windows give up CRLF line endings, it will be immediate

Firtstly writing Qt desktop apps in Python is pretty popular so we don’t need to stick with C++ to write Qt app. It is hard to understand people cares about memory useage when desktops nowadays have a lot of RAM. What average Electron apps

by kbumsik 8y ago
Wow. I’m wondering why it is popular in China. There should be something other than resistance.

by kbumsik 8y ago
By looking at README and the original Gogs project, it looks like these projects are gaining some attention in China. It is quite interesting for me when these are written in Go which is Google’s proejct blocked by the Chinese government.

Almost, when switching from PyQt4 to PySide 1. It was roughly equivalent with some minor differences. It was much less work than switching Python 2.7 syntax to 3. There are some bindings as well [1]. I don't know much detail about PyQt

by kbumsik 8y ago
As you can see, Qt for Python is not yet stable release. So you will want to use PyQt5 first. I remcommand PyQt5 because there are more resouces available on the internet now. PyQt5 and Qt for Python is a 1-to-1 binding to the original Qt a

Why not just looking at the source code? I attached an example of Arduino Zero varients [1] (it is directly from Atmel's SDK.) It is quite straightforward to see what happends before main(). In embedded system, you can even change it e

I don't know much about AMD64 but if the arguments are passed to registers then how it is possible to retrieve argc/argv later, as other functions likely to touch registers?
866.
by kbumsik 8y ago
It is certainly possible to do this with C by editing a startup code. In embedded system, a source code of startup is provided and exposed by manufacturer's SDK so it is quite straightforward to do this. Besides that, I can't see
867.
by kbumsik 8y ago
In embedded system, many manufacturer’s default startup code does not even implement argc/argv. In that case this won’t work, or you need to implement your own startup code.

Yeah I personally see Qt code is much cleaner.

No. Please. Struct bitfields may be useful to save memory (e.g. 1 bit for boolean-like variable) but don't rely on it when accessing register data or implenting protocols. The biggest issue with struct bitfields is that its implementat
